What are the precautions for installing solar water heaters

Many people like to use solar water heaters, but they still need to be installed after purchasing solar water heaters. What are the precautions for installing solar water heaters? What methods do people have when buying solar water heaters?

What are the precautions for installing solar water heaters?

1. Pipe selection

The water temperature of the solar water heater can reach above 95 degrees Celsius under the highest condition, which indicates that it is easy to burn the vacuum tube. Therefore, in order to prevent the occurrence of aging and softening of the vacuum tube, when choosing a water heater, you must choose aluminum-plastic tubes as the material of the vacuum tube, which can increase the service life of the water tube. Some manufacturers use polystyrene insulation materials for vacuum tubes, which are relatively inexpensive, but such insulation materials will form larger gaps in the insulation layer, causing serious shrinkage and deformation, and the transportation of hot water will be very inconvenient. .

2. Solar reflector installation

I don’t know if you have noticed that when installing solar water heaters, the staff will install solar reflectors, but this reflector is not actually very useful. If you remove it, it can still be a great deal. Go to the ground to improve the windproof performance of the equipment. If you don't remove it, you need to pay special attention to the installation situation, to firmly secure it to the roof, which can resist the invasion of typhoons. In addition, in the event of a typhoon, it is best to fill the solar water storage tank with water. This type of equipment is more resistant to wind.

3. Install lightning rod

To ensure the service life of the solar water heater, the lightning protection design must be done when the water heater is installed. After the user purchases the water heater, he can ask the installer to install a lightning rod next to the water heater so that the lightning rod is more than half a meter higher than the top of the water heater. In addition, the water storage tank of the water heater must be grounded, and special attention must be paid to the connection of indoor outlet water and electric potential. At the same time, it is best not to use a water heater during thunderstorms to avoid injury.

What are the purchasing methods for solar water heaters?

1. The type of collector.

After basically clarifying the size of the solar collector, the type of solar collector should be selected. The current types of solar collectors in my country are mainly flat plate and vacuum tube type. Flat solar energy is beautiful and practical, while vacuum tube solar energy is more economical. Users can choose according to local climate characteristics and required hot water temperature.

2. Collector tube

The collector tubes are divided into all-glass vacuum tubes that take water and heat pipe vacuum tubes that do not take water. Heat pipe vacuum tubes are divided into single-wall heat pipes and double-wall heat pipes. The double-wall heat pipe has the characteristics of high thermal efficiency, high quality, long service life, and economical benefits. Single-wall heat pipes are characterized by intuitiveness, and are sealed by metal materials, and their stability is worse than that of double-wall heat pipes with glass sealing.

3. Water storage tank size

First of all, the average amount of hot water used and the number of long-term users should be clarified, and then the total amount of hot water per day should be calculated. It can be selected according to the specific hot water demand of the family and the water consumption in winter as an important criterion. Individual bathing needs a figure of 50 liters of hot water to estimate, this kind of basically can choose a water heater with a suitable volume.
